CFS Senneterre, initially called RCAF Station Senneterre prior to 1967, was a long-range radar and Ground Control Intercept station, part of the Pinetree Line radar defence network, situated 40 miles (64km) north of Val-d'Or, Quebec. Situated atop Mount Bell, east of the town of Senneterre, Quebec, construction started in 1950. By 1953 the 34 AC&W Squadron became operational. From 1968 to 1973 Senneterre was the backup to CFB North Bay, the regional command post; in the event it was incapacitated by a nuclear strike, Senneterre was designated an Alternative Command Post (ALCOP). In 1988 the station was deemed no longer necessary as a long-range radar, and closed.
